5 Accessibility

This chapter documents support for accessibility in the RPASCE Configuration Tools. It describes the support for accessibility and assistive technologies within the underlying platform used by the Configuration Tools. Additionally, it details accessibility support and considerations built into the application beyond the capabilities of the underlying platform.

Java Swing and the Java Access Bridge

The RPASCE Configuration Tools is built using the Java Swing platform as its underlying technology. The Java Swing platform, which form a part of the Java Foundation Classes framework, provide robust support for accessibility and assistive technologies.

This support takes the form of full support for the Java Accessibility API, a set of APIs that provide the ability for assistive technologies to interface with an application programmatically and for an application to adapt to accessibility settings made within the Windows operating system.

This support includes:

• Support for alternate input devices

• Support for keyboard-only operation of the application

• Support for high contrast and larger text display

• Support within each UI component for accessible roles, labels, and descriptions to support assistive technologies such as screen readers

In order to provide integration with assistive technologies and accessibility settings of the Windows environment, Java contains a supplemental library called the Java Access Bridge. This supplemental library must be enabled in order for it function.

Information about the Java Access Bridge - including instructions on how to enable it – can be found at:

Accessibility Support with the RPASCE Configuration Tools

In addition to the accessibility support provided by the Java Foundation Classes framework, the RPASCE Configuration Tools provide the following accessibility features:

• All components have a text identifier, either in the form of a component label or an accessible tooltip.

• Color contrast has been evaluated across the application in order to ensure a contrast ratio of 4.5:1. In places where a ratio of 4.5:1 could not be met, alternative cues such as the use of an italic font style provide a secondary visual indicator.

• The Configuration Tools supplement visual indications of errors with a centralized task list containing records of validation issues to assist in error identification and correction.

• A consistent keyboard focus navigation policy has been ensured across the Configuration Tools (See note on traversal mechanics in next section.)

Keyboard Focus Traversal Considerations

The RPASCE Configuration Tools has a complex component layout, consisting of internal windows and multiple compound components such as tables and trees. In order to provide a consistent mechanism for keyboard traversal, the following conventions exist.

• The focus traversal key (Tab) will iterate in a logical fashion through the components according to their layout.

• When the focus enters a compound component type such as a table, the focus traversal key (Tab) will retain focus within the component, wrapping from the last component in the inner sequence to the first. Use of Ctrl+Tab moves the focus out of the inner focus cycle group to the next component in the outer cycle group (for example, from an embedded table to the component following the table according to the traversal order).

• Within certain compound components such as trees, menus, and tab groups, use of the arrow keys allows internal navigation, while Tab moves the focus to the next component according to the traversal order.

• Once focus has entered one of the internal frames of the application such as the Measure Tool or Rule Tool, it cycles through the components of that tool. In order to transition out of the embedded frame back to the enclosing workbench, make use of Ctrl+Tab when the focus is on the initial component of the embedded frames traversal order (in most cases the initial button in the toolbar).

• At all times, the Alt key activates the main menu bar while retaining keyboard focus on the currently focused component. Navigation of the menu can be accomplished using the arrow key or, when applicable, mnemonics or accelerators.

Keyboard Shortcuts

Keyboard shortcuts enable users to work efficiently. Instead of using a mouse, users with mobility or vision disabilities can use keyboard shortcuts to navigate through the software. While the previous Keyboard Focus Traversal section describes shortcuts related to focus traversal, this section lists additional frequently used shortcuts for accessing ConfigTools GUI components.

Note the following:

• A plus sign (+) in a shortcut means that users need to press the multiple keys at the same time.

• If the focus is inside an editable text component or selectable component such as button etc, use Shift +Tab to move focus to the previous component, and Tab to the next component.

• When the focus is on a menu, users can use Mnemonics to activate its menu item. The menu item mnemonics is the underscored letter in the menu item name.

• To open any menu item directly, use Alt + Menu mnemonic + Menu Item Mnemonic. For example, to open the Domain configuration dialog directly, use Alt + F + W shortcuts.

• When a button has the focus, typing the Space key is equivalent to a mouse click on the button.
